Japanese acupuncture significantly differs from other styles in its delicacy.  The needles used are barely thicker than a human hair–much finer than those used in Chinese Acupuncture–and they are usually inserted just 1 to 2mm or less, with an absolute minimum of manipulation. These techniques demand far greater precision and care than other forms of acupuncture. Whilst this is a challenge for the practitioner, it is a welcome bonus for the recipient in that it is usually completely painless.
